CAN-CLOSURE.

SPECIFICATION forming part of Letters Patent No. 769,899, datedSeptember 13, 1904.

Application filed February 14, 1902. Serial No. 94,041. (No model.)

To all whom, it Wtay concern.-

Be it known that I, FRANooIs GINET, acitizen of the Republic of France,and a resident of Chambry, France, have invented certain new and usefulImprovements in Can-Closures, of which the'following is a specification.

My invention relates to improvements in cans having soldered tops; andthe object of the invention is to provide an improved form of can-top ofthe rip-opening typethat is, of the type in which the can can be openedby winding up a strip of metal upon a suitable key.

The invention resides in the particular con struction hereinafterdescribed, and particularly set forth in the claim.

I have illustrated the invention in the accompanying drawings, in whichFigure 1 represents a central vertical section through the upper portionof the can. Fig. 2 is a perspective view of the upper part of the can,showing the manner of opening.

Referring to Figs. 1 and 2, the upper end of the can, as indicated at 6,and a cover which is applied thereto is shown as consisting of two parts1 and 2, connected by a band 3, which overlaps the adjoining edges ofthe parts 1 and 2 and is soldered thereto. The part 1 is in the shape ofa ring provided with an open center and having its outer edge clamped orfolded around the upper edge of the can-body. The inner edge of the ringis depressed below the upper end of the can-body, but lies in ahorizontal plane. The central portion or disk 2 has its peripheral edgeportion 2 struck downwardly, as shown. Thus when the depressed portion 1of the ring 1 and the portion 2 of the disk 2 are held in alinement ashallow depression is formed. WVithin this shallow depression is locatedthe joining-strip 3, which is simply a circular strip of metal havingone end slightly overlapping the other. This, it will be seen, overlapsboth portions 1 and 2 and is soldered to both, as indicated clearly inFig. 1, thus securing the parts effectively together.

When, however, it is desired to open the can, I a suitable tool, such asthat indicated at c in Fig. 2, is connected to the free end 19 of thestrip 3, and by winding up the key the strip may be .pulled away fromthe surfaces to which it is soldered, and thus the disk 2 left entirelyunconnected with the ring 1.

I am aware that it is not new to embody a wire or ripping-strip in orbeneath the metal of the can so that it has a ripping efiect to cut orsever the joint or corresponding portion of the can in opening the same.I am also aware that it is not new to provide parallel weakened linesand to rip out the portion of metal lying between said parallel lines;but my invention is clearly distinguished from this in that I provide acan-top of two parts having their edges adjacent to each other, but notin contact, the connecting and closing effect being secured by a stripof metal which overlaps the said adjacent parts and has its facesoldered to the faces of the said parts, so that when the strip ispulled away the parts are left entirely unconnected without any part ofeither being torn or ruptured in any way.

By constructing my can top or cover as above described I avoid thenecessity of having the ripping-strip sever the tin of the cover, whileat the same time after the soldered strip is removed the inner partisleft entirely disconnected with the outer. There is therefore nodanger of breaking of the ripping-strip before the opening of the can iseffected.

A further advantage of my construction lies in the fact that as theinner part is smaller than the outer part the two parts may be struck atone and the same time out of a single sheet of metal without waste,while by 10- cating the joining-strip in a depression, as described, thestrip does not project above the top of the can, but is protected andspace saved when the cans are piled one above the other.

A still further advantage in my construction is that I have found itmore convenient to manufacture and easier to assemble, and hence moreeconomical, than any rip-openers of which I am aware.

Having thus described my invention, what I claim is The combination witha metallic can-body forming an annular channel and a flat annular bandof sheet metal soldered to the bottom of said channel and having aprojecting end for engagement With a suitable key, substan I tiallyasdescribed.

In witness whereof I have hereunto set my hand in presence of twoWitnesses.

FRANCOIS GINET.
